CAPSULE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 276,281, dated April 24, 1883,

i Application inea November 21, 1882. (No maar To all 'whom it may concern:

4 Be it known that I, CHARLES F. PURDIE, of Detroit, county of Wayne, State of Michigan, have invented a new and useful Improvement in Capsule-Machines; and I declare the following to be a full, clear, and exact descrip-V tion of the same, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which .form a part of this specification.

My invention consists in the combinations of devices and appliances hereinafter speci fied, and more particularly pointed out in the claims. t

In the drawings, Figure l is a vertical sec-. tion ofa device embodying my invention, showing a capsule-pin in elevation. Fig. 2 is a plan view of the top of the arbor or tube, showing its interior cushion. Fig. 3 is a variation of a device shown lin Fig. l. Fig. 4t is a plan view of the top Fig. 5 is a variation of the same.

Heretofore it has been customary in the use of capsule-machines to wipe the mold-pins by 4hand for the purpose of cleaning and greasing them-a process requiring muchV labor and expense, and one which cannot be conveniently employed `Where the mold-pins are ar-` ranged very close together, as is contemplated 30v in devices 0f this nature for which I have previously made` application for Letters Patent o the United States.

The object of my invention is to provide means for wiping and greasin g capsule-molds, though they may be located near to each other, and dispensing with the necessity of wiping said molds by hand, thus materially expediting and cheapening this feature of the work. I accomplish this result by means ot' one or more sleeves or tubes ,provided at one end with an interior cushion of' any suitable soft and elastic material, adapted to bereciprocated and revolved by any proper mechanism in such a manner as to enga-ge with one or more capsuie-molds.

In carrying out my invention, A represents a mold-plate provided with one or more capsule-molds, a.

B represents one or more sleeves or tubes, preferably provided with one or more" slots, b,

extending longitudinally with the sleeve, on

the end which engages with the mold-pins. These slots give elasticity to that end of the tube and assist in securing the interior cushion, b', in place and add to its efficiency, though said slots may be dispensed with. The interior cushion may be madeof cork, rubber,

felt, or other suitable material, permitting itsV ready passage over the molds and adapted to press up closely upon them. As shown in Fig. 1, the tubes B are secured to a'movable plate, G, preferably by means of a screw, c, adapted to revolve in the plate C. The tubes are adapted to be reciprocated through the stationary plate D by any suitable mechanism, in such a manner as to engage the cushion h upon the molds a. They are also adapted to be rotated by means of the spiral slot b2 andl the xed pin d when reciprocated. As shown, the spiral slot is in the sleeve or tube B; but it is evident that the spiral slot may be constructed in the plate D and the pin secured to the sleeve B. Y

It is evident that gby projecting the plate C forward or upward, as the case maybe, the tube B, with its interior cushion, b', is pressed over the end of one of the capsule-molds, and is at the same time revolved about the said mold.

The pin is thereby wiped. This interior cushion is intended to be kept suitably greased for the purpose of greasing the molds as they are wiped.

I would have it understood that I do not confine myself to the use of the moving plate C, as the sleeves B can bereciprocated through the plate D and upon the molds without be ing attached to said plate, the plate being entirely dispensed with. Nor do l confine myselt` to the use of a spiral slot, b2, to revolve said tubes, as it is evident that they may be revolved by other mechanical means-as, for example, by manifold converging rods E, as used in gang-drills, dovetailing-machines, or by other suitable mechanism adapted for the purpose where the tubes are brought so close together as not to admit of the direct use of belts, pulleys, or gears. in Fig. 3, need not be stationary, but may move with the tube, or the tube may be reciprocated through it, as in Fig. 1, while it remains stationary. In case the tube is not reciprocated- The plate D, as shown.

, supporting and operating the sleeve or tube to ders or collars d above the plate, and with a collar, d2, below the plate. Nor do I confine myself to any particular method of securing the interior cushion in place in the end of the tube. It may be secured, for example, wholly in the interior, as shown in Fig. 2; or the end of the tube may have a suitable number of segments and the cushion secured, as shown in Fig. 4, partly within the tube and over the ends of the segments; or suitable material may be reefed back and forth through the slots, as shown 'in Fig. 5.

1. The combination of a sleeve or tube, a wiper-cushion carried thereby for surrounding and wiping a capsule-mold pin, and means for wipe the mold-pin, substantially as described.

2. The combination, with a sleeve or tube and a wipercushion for surrounding and wipingv a capsule-mold pin, of means for reciprocat ing and rotating the sleeve or tube, substantially as described.

3. The combination, with a perforated plate, a sleeve or tube arranged therein, and a wipercushion on the sleeve or tube for surrounding and wiping a capsulemold piu, of means for reciprocating and rotating the sleeve ortube, substantially as described.

4. In a capsule-machine, the combination, with a perforated plate, of one or more longitudinally-slotted sleeves or tubes, in combination with suitable reciprocating mechanism, said tubes provided with an interior cushion adapted to en gage one or more molds, substantially as and for the purpose described.

5. In a capsule-machine, the combination, with a sleeved plate, of one or more sleeves or tubes adapted to be. reciprocated and revolved by any suitable mechanism, said tubes constructed with one or more longitudinal slots extending from one end of the tube a suitable distance, and provided with an interior elastic cushion adapted to engage one or more capsule-molds,substantially as and for the purpose described.

In testimony whereof I sign this specification in tlie presence ot' two witnesses.
